Question

Complete each of the following exercises from the Deitel book, using the indicated C# project names. You should use a .NET Framework Console application type for each project. All projects should be part of a single solution named: Cs2Apps.

How to setup multiple Projects in one Visual Studio Solution

When creating the first Project, make sure to uncheck the box for putting the solution and the project in the same folder. This will create a separate folder with the solution file by itself and the first project in a folder under that. For each subsequent project, use the "File->Add->New Project" to add each project to the **same** solution.

To switch projects among those listed in the Solution Explorer window, right click on the project and select "Set as StartUp Project". The selected startup project will display as bold text in the Solution Explorer window.

4.11 - Employee Class (Project Name: EmployeeDB) - Create a class called Employee that includes three pieces of information as either instance variables or auto-implemented properties - first name (type string), last name (type string) and a monthly salary (decimal). Your class should have a constructor that initializes the three values. Provide a property with a get and set block for any instance variables. If the monthly salary is negative, the set block should leave the instance variable unchanged. Write a test driver program for Employee that demonstrates the Employee class capabilities (use Program.cs for this). Create 3 Employee objects and display each object’s yearly salary. Then give each Employee a 10% raise and display each Employee’s yearly salary again.

6.16 - Displaying a Bar Chart (Project Name: BarChart) - One interesting application of computers is to display graphs and bar charts. Write an app that reads three numbers between 1 and 30. For each number that’s read, your app should display the same number of adjacent asterisks. For example, if your app reads the number 7, it should display 7 stars: *******

Dear Student ,

As per requirement submitted above kindly find below solution.

4.11 - Employee Class (Project Name: EmployeeDB)

Here new console application in C# is created using visual studio 2019 with name "EmployeeDB". This application contains below classes.

Employee.cs :

//namespace
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//application namespace
namespace EmployeeDB
{
class Employee//C# class
{
//auto-implemented properties
public string firstName { get; set; }
public string lastName { get; set; }
private decimal salary;

//constructor
public Employee()
{
this.firstName = "";
this.lastName = "";
this.salary = 0;
}
//setter and getter method for salary
public decimal Salary
{
get
{
return salary;
}
set
{
//checking salary
if(value>0)
{
this.salary = value;
}
}
}

}
}
*********************************

Program.cs :

//namespace
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//application namespace
namespace EmployeeDB
{
class Program //C# class
{
//Main() method , which is entry point of the application
static void Main(string[] args)
{
//creating object of Employee class
Employee e1 = new Employee();
e1.firstName = "Virat";//set firstName
e1.lastName = "Kohli";//set lastName
e1.Salary = 10000;//set Salary
//print e1 details
Console.WriteLine("Employee 1 :" + e1.firstName + " " + e1.lastName +"\n\tYearly salary : "+(e1.Salary*12));
//creating object of Employee class
Employee e2 = new Employee();
e2.firstName = "KL";//set firstName
e2.lastName = "Rahul";//set lastName
e2.Salary = -10000;//set Salary
//print e2 details
Console.WriteLine("Employee 2 :" + e2.firstName + " " + e2.lastName + "\n\tYearly salary : " + (e2.Salary * 12));
//creating object of Employee class
Employee e3 = new Employee();
e3.firstName = "Ajinkya";//set firstName
e3.lastName = "Rahane";//set lastName
e3.Salary = 5000;//set Salary
//print e3 details
Console.WriteLine("Employee 3 :" + e3.firstName + " " + e3.lastName + "\n\tYearly salary : " + (e3.Salary * 12));
Console.WriteLine("---------Employee details after giving 10% salary hike----------");
//print e1 details
decimal e1Salary= (e1.Salary * 12) * (decimal)0.10;//calculating yearly 10% increment
Console.WriteLine("Employee 1 :" + e1.firstName + " " + e1.lastName + "\n\tYearly salary : " + (e1Salary + (e1.Salary * 12)));
//print e2 details
decimal e2Salary = (e2.Salary * 12) * (decimal)0.10;//calculating yearly 10% increment
Console.WriteLine("Employee 2 :" + e2.firstName + " " + e2.lastName + "\n\tYearly salary : " + (e2Salary + (e2.Salary * 12)));
//print e3 details
decimal e3Salary = (e3.Salary * 12) * (decimal)0.10;//calculating yearly 10% increment
Console.WriteLine("Employee 3 :" + e3.firstName + " " + e3.lastName + "\n\tYearly salary : " + (e3Salary + (e3.Salary * 12)));
//used to hold the screen
Console.ReadKey();
}
}
}

==================================

Output :Run application using F5 and will get the screen as shown below

Screen 1:Program.cs
